It seems more like additional parallel storage mechanisms to me.

I agree that we are introducing additional ones of those. But if we compare
to other APIs in other platforms, it is common to allow passing closures
that are passed back with callbacks. More common than allowing identifiers
to be passed in which then require the callback to use the identifier to
look up data in a separate storage mechanism.
